1'0 all whom it may concern.-

Be it known that l, Ronnn'r .ilARVEY Mcf DOWELL, a citizen of the United States, re-- Q siding at Alliance, in the county of Stark and State of-Ohio, have invented a newaud useful lm rovement in an Automatic Electrical Cut-O of which the following is o specification.

This invention relates to en nutonmtic cutoff or circuit breaker, for use in connection with a purifier and filter, described in s sepsrste application, and combines a valve cut oil, for controlling the discharge of s fluid from a filtering cheinber end'the simultaneone making and breaking of an electrical circuit.

In the purifier and filter with which this invention is used the liquid before being passed to the filtering chamber is subjected to the action of an electric-til circuit and such actionif maintained,will result in the boiling of the water and injury to the filtering stone em loycd in the filter.

he object of the present construction is to rovide means whereby electrodes employed in the purifier are placed in on electrical circuit only when liquid is being drawn from the filteringchuniher and the circuit broken as soon as the flow of liquid is steppe i. This has formerly been accomplished hy providing a suitable switch adjacent the (lPVlPO, which switcl i was intended to be operated to break the c rcuit when nsu'llicient amount of liquid had been (lI'lDNIl from the filter," but it left on, more or less diunoge has been caused.

- the faucet shown in section.

This invention consists of the combination with n discharge faucet with on electrical switchhuving its operative part connected to the valve operating moons of the faucet whereby the electrical circuit is broken when the valve is closed, and completed when the valve is opened.

l into the outer end of which is threaded a faucet or bih B, which has a valve seat B,-

A suitoble'valve C and is adapted to formed at its inner end. is placed in the pi e A not with the scat The bib or faucet B has an upwardly ex- 1 tending projection D over which is threaded rs cup I) and the projection D is provided with an interior annular shoulder A cylindrical block or shalt E rotates within the projection l) and bears upon the shoulder E. The block or shaft E is provided with a reduced portion E" which extends down wardly below the shoulder I) into the body portion of the fsucet B.

A stem E extends upwardly from the block E and on the axial line of the said block and through the cap D, and is pro E by means of? which the stem and block may be rotated. A suitable angled shaft F is connected at its upper endeccentrieall to the bottom of the extension E of the b ock E and extends downwardly throu h the lowerwoll of the bib or faucet and lies its lower end portion fitted into a semi-circular opening G. formed centrally in a flanged disk G. p

The disk G. is formed of hard rubber or other suitable insulating inzilierinl and a semicircular bressoontsct plate'G is secured to the underside of the disk resting within and bearing upon the fiange. The space between the ends of the said contact late ere rests within and against the depending :llenge of the disk G. I i of the switch and the stationary part is formed to a suitable disk ll also of'insuluting tion l around the grciiter portion of w iich extends a. contact plate ii and between the ends of said plate and spaced from each end is a. short curved cpntuct plate ll; Suitable binding posts II are carried by the disk H and-electrical conductors II lead from the said binding osts. I. I

On the um 01' side of the disk ii. is formed a. transverse ridge H having a longitudinal bore therethrou h and a metal rod oi-wire H, has one .em fitted into the bore of the ridge H and its opposite'end fitted into a. suitable perforation or socket formed in the filter chamber A, and intermediate its ends vided at its upper end with it suitable handle.

bridged by it suitable insulator l" which'also This forms a. movable part materiel having a central circular raised or the saiu.w1re or rod is bent to form a loop H which serves as a support for the. conductors H? as shown in Fig. v I

-To the valve 0 is connected a valve stem J, which works through a suitable web J, and is pivotally connected to the shaft F. The flanged disk G fits down over the central raised portion H of the disk H and also over the contact plates H and H and the inner face of the contact plate G2 slides upon outer faces of the contact plates or rings H and H ,7

It will be noted from Fig. 2 that one of the binding posts H is in electrical contact with the contact plate H and the other binding post H is in contact with the semi-circular ring H The parts are so assembled that 1 when the handle E is thrown into such a position that the valve C is drawn to its seat, each of the s aces between the plate H and H will be bridged by the insulating strip G but whenever the handle is turned so as to move the valve C away from its seat, the contact plate G will be in engagement with the plate H and at least one of the end portions of the contact plate H bridging one of the sp ices between the contact plates H and H tllLs completin the circuit between the two binding posts If.

It will be obvious that the rod H not only serves as a support for the disk H but also prevents rotation of the same when the disk G is rotated. In operation whenever a liquid is bein drawn from the filter an electrical circuit will be'established between the bindingposts H and acurrent will be permitted to pass over the conductors H to certain electrodes in a purifying chamber which electrodes, together with the electrical circuit are shown and described in a separate application.

' It will be further noted that the wire H is connected to the body of the filter and that the movable member of the switch is carried by the faucet or bib, and'the latter is carried by the top or cover of the filter. When therefore the top of the filter is removed the stationary part of the switch to which the wires are connected is not disturbed by removing either the top of the filter or the faucet.

' Having thus fullydescribed my'invention, what I claim as new and desire to secure by Letters Patent, is

1. In combination with a faucet, a valve th jn, an angled rod arranged transversely in thefaucet, and extending outwardly and downwardly, an electrical switch oper ated by said ro a hand lever adapted to rotate said rod, and means connecting the.valve to therod. a

21A device of the kind described comprising a-faucet, a valve, a valve stem, said faucet having a covered projection, a shaft therein having a reduced portion extending into the body of the faucet, a stem carried by the shaft, a handle thereon, an angled shaft connected at its upper end eccentrically to the shaft end, the an' led shaft extending downwardly through t e lower wall of the faucet, the valve stem being pivoted to said angled shaft, and electrical circuit making and breaking means operatively connected to the lower end of the angled shaft.

3. A device of the kind described comprising a switch having a stationary-portion, a cut contact ring carried thereby, a contact plate arranged between the ends of the ring and spaced therefrom, a rotatable disk having a segmental contact plate adapted to slide upon the outer face of the contact plate carried by the fixed, portion, a dischar 'e faucet having a valve therein, a cranksha t having one end connected to the rotatable disk, a valve stem pivotally connected to the angled portion of the shaft, and means for rotating said shaft.

4; A device of the kind described comprising a discharge faucet, a valve seat, a valve movable toward and away from the seat, an electric switch comprising stationary contact plates spaced a art, and a rotatable semi-circular contact p ate adapted to slide upon the stationary plates and bridge the space between them, and common means for rotating the rotatable contact plate and moving the valve as and for the purpose set forth.
